// Most icons are embedded SVG. Icons are embedded using Grunticon. We are using
// the original SVG icons from Drupal core, however the width and height
// attribute have been replaced with a viewBox attribute so we can scale them
// properly with CSS. Embedded SVG has the advantage of being styled with CSS,
// and by using Grunticon JS loading we negate most of the bloat and overhead
// associated with embedding SVG files. For the buttons (orientation toggles &
// menu click handles), and for sub-menu indicators we use a custom font icon
// that is tiny and only includes four icons. We rotate and color these in CSS
// as required.
